In this paper, we present theoretical and numerical modeling results for thermal analysis of Lithium ion (LiFePO4) battery cells during discharge (0.2C, 0.5C, 1C). Thermal management is important for many reasons, including thermal runaway, performance and maintains a constant temperature during the operating, security, lifecycle. However, in a battery pack, the batteries are stacked against each...
Evaluating the emission performance of a diesel engine, ESC testing is requisite. Traditional equipments are inefficient, special equipments are relatively expensive. In order to solve this problem, the author processed independent equipment into the node of a distributed network and developed an ESC testing system through virtual instrument technology. This system was used in the 4JB1 diesel engine...
To control cylinder pressure in diesel engine multiple injections is presented by using new control strategy. The improvements of the solenoid injector and of the electronic control unit of the present common rail (CR) injection system allow the use of multiple sequential injections. Two injections are included in the new injection strategies. The first injection is the pre-injection and at 33 CAD...
Increasing demand of electronic control and operation condition monitor in diesel engine require to decrease acquisition system for on-line diagnosis and optimize system configure, it is presented the acquisition method including data process and data communication, on this basis, acquisition system oriented to diesel engine control is developed, hardware and software of this system is designed: Fiber...
To meet the demand on precise control of electronic control in diesel engine, study on electronic control of cylinder pressure feedback in common rail diesel engine is made. On the basis of brief analysis for cylinder pressure physical meaning, mechanism and sketch of electronic control based on cylinder pressure feedback is presented, pressure characteristic variable orienting to control is provided,...
